Time-to-treatment in traumatic brain injury: unraveling the impact of early surgical intervention on patient outcomes

2025 , María Inés Egas Terán , González Andrade, Fabricio

Background: Traumatic brain injury (TBI) remains a major public health concern due to its high morbidity and mortality. The ‘golden hour’ principle suggests that outcomes improve with rapid access to definitive care. However, the role of prehospital transport time in TBI prognosis remains unclear, particularly in resource-limited settings. This study evaluates the relationship between hospital arrival time and functional prognosis in TBI patients. Methods: A cross-sectional observational study was conducted in two Ecuadorian trauma centers from 2017 to 2020. Patients were categorized into early (<8 h) and late (>8 h) hospital arrival groups. Demographic, clinical, radiological, and surgical variables were analyzed. The primary outcome was functional prognosis, measured by the Glasgow Outcome Scale (GOS) at hospital discharge. Logistic regression was used to adjust for confounding variables. Results: A total of 373 TBI patients were analyzed. The early-care group presented with more severe injuries, lower Glasgow Coma Scale (GCS) scores, and higher rates of abnormal pupillary responses. Late-arriving patients had better initial neurological status and were more likely to have received prehospital stabilization. Surgical intervention was delayed in both groups, with 67.8% of early-care patients undergoing surgery 8–24 h post-trauma. Adjusted analysis showed no significant difference in functional outcomes between early and late-care groups (OR 1.95, p = 0.08). Conclusion: Hospital arrival time alone does not significantly influence TBI outcomes. Instead, prehospital stabilization, initial GCS, and timely surgical intervention are stronger prognostic factors. Trauma care strategies should prioritize improving prehospital management and reducing in-hospital delays rather than strictly adhering to the ‘golden hour’ paradigm.

Demographic, Functional, and Risk Factors Characterization in Ecuadorian Mestizo Patients With Microtia: A Retrospective Study

2024 , González Andrade, Fabricio , Fausto Coello , Ramiro López-Pulles , Guillermo Fuenmayor , Edwin Andrade , Henry Vásconez

Objective: This paper compares demographic, morphological, functional, and risk factors between isolated and familial forms of microtia in Ecuadorian mestizo patients. Methods: The authors did an epidemiological, and retrospective study with 112 patients divided into isolated microtia (n = 91) and familial microtia (n = 21). Patients with syndromic microtia were not included. Results: In isolated microtia, the mean age was 11.80 ± 16.9, and the most prevalent age group was from 5 to 9 years, with 45.0%; males were 58.2%, and 91.2% of patients were born in a city above 2500 meters about sea level. In familial microtia, the mean age was 15.57 ± 17.2. There were no statistically significant differences between the analyzed variables. In isolated microtia, 41.8% of patients had bilateral involvement, 40.7% had grade 1 microtia in the right ear (RE), and grade 1 in the left ear was 47.3%; external auditory canal atresia of RE was present in 62.6%, and in left ear in 31.6%. External auditory canal atresia sidedness was mostly unilateral in both groups. Most patients did not have tags or pits (78% and 81% in RE and 85.7% and 71.4%). Most patients had moderate hearing loss in both ears. Conclusion: The authors found an association between both microtia forms with external auditory canal atresia in RE; only 20% of patients had unilateral auricular tags or pits in both groups. The authors also found a high incidence (18.75%) of familial microtia, which suggests a distinct pathological genetic component than the more prevalent isolated cases. The authors found a high association of microtia cases from the Ecuadorian highlands above 2500 meters about sea level (over 90%). The presence of “social” intake of alcohol during pregnancy showed over twice the chance of having a child born with microtia.
